A month has passed since Mrs. Taeko has lost her husband. Ever since then she has been wearing a black dress/ mourning dress. In order to comfort her Toshiki and Miyuki visit her every day. On one of those days, the deceased husband's stepbrother is supposed to come over too. He has been living overseas and so far has not been able to meet Mrs. Taeko. Mrs. Taeko's needs for a man in turn are becoming bigger and bigger. At last, she cannot hold back any longer and begins to seduce Toshiki. Meanwhile, Kaoru who finally arrives from abroad is now able to do all the paperwork. This means however he will have to stay with Taeko-san for a longer time.
